Debian Security Advisory DSA 3861-1 (libtasn1-6 - security update)

Jakub Jirasek of Secunia Research discovered that libtasn1, a library used to handle Abstract Syntax Notation One structures, did not properly validate its input. This would allow an attacker to cause a crash by denial-of-service, or potentially execute arbitrary code, by tricking a user into...

UBUNTU-CVE-2016-9939

Crypto++ aka cryptopp and libcrypto++ 5.6.4 contained a bug in its ASN.1 BER decoding routine. The library will allocate a memory block based on the length field of the ASN.1 object. If there is not enough content octets in the ASN.1 object, then the function will fail and the memory block will b...

openssl: Memory corruption in the ASN.1 encoder

A flaw was found in the way OpenSSL encoded certain ASN.1 data structures. An attacker could use this flaw to create a specially crafted certificate which, when verified or re-encoded by OpenSSL, could cause it to crash, or execute arbitrary code using the permissions of the user running an...

Microsoft Windows - LSASS SMB NTLM Exchange Null-Pointer Dereference (MS16-137) Exploit

Exploit for windows platform in category dos / poc MS16-137: LSASS Remote Memory Corruption Advisory Title: LSASS SMB NTLM Exchange Remote Memory Corruption Version: 1.0 Issue type: Null Pointer Dereference Authentication: Pre-Authenticated Affected vendor: Microsoft Release date: 8/11/2016...

kernel: Kernel panic and system lockup by triggering BUG_ON() in public_key_verify_signature()

A syntax vulnerability was discovered in the kernel's ASN1.1 DER decoder, which could lead to memory corruption or a complete local denial of service through x509 certificate DER files. A local system user could use a specially created key file to trigger BUGON in the publickeyverifysignature...

Oracle E-Business Multiple Vulnerabilities (October 2016 CPU)

The version of Oracle E-Business installed on the remote host is missing the October 2016 Oracle Critical Patch Update CPU. It is, therefore, affected by multiple vulnerabilities : - A heap buffer overflow condition exists in the OpenSSL subcomponent in the EVPEncodeUpdate function within file...

openssl: ASN.1 BIO handling of large amounts of data

A denial of service flaw was found in the way OpenSSL parsed certain ASN.1-encoded data from BIO OpenSSL's I/O abstraction inputs. An application using OpenSSL that accepts untrusted ASN.1 BIO input could be forced to allocate an excessive amount of data...

Blue Coat ProxyAV 3.5.x < 3.5.4.1 Multiple DoS Vulnerabilities

According to its self-reported version number, the Blue Coat ProxyAV firmware installed on the remote device is 3.5.x prior to 3.5.4.1. It is, therefore, affected by the following vulnerabilities in the bundled version of OpenSSL : - A NULL pointer dereference flaw exists in file rsaameth.c due t...

SUSE SLED12 / SLES12 Security Update : libtasn1 (SUSE-SU-2016:1601-1)

This update for libtasn1 fixes the following issues : - Malformed asn1 definitions could have caused a segmentation fault in the asn1 definition parser bsc961491 - CVE-2015-3622: Fixed invalid read in octet string decoding bsc929414 - CVE-2016-4008: Fixed infinite loop while parsing DER...

SUSE SLES11 Security Update : libtasn1 (SUSE-SU-2016:1600-1)

This update for libtasn1 fixes the following issues : - Malformed asn1 definitions could have caused a segmentation fault in the asn1 definition parser bsc961491 - CVE-2015-3622: Fixed invalid read in octet string decoding bsc929414 - CVE-2016-4008: Fixed infinite loop while parsing DER...

Objective Systems ASN1C Heap Buffer Overflow Vulnerability

ASN.1 is a set of standards that describes the notation for representing, encoding, transmitting, and decoding data.ASN1C can generate high-level language code according to the ASN.1 syntax. An integer overflow vulnerability exists in ASN1C for C/C++ version 7.0.2, in the...

CVE-2016-5080

Integer overflow in the rtxMemHeapAlloc function in asn1rta.lib in Objective Systems ASN1C for C/C++ before 7.0.2 allows context-dependent attackers to execute arbitrary code or cause a denial of service heap-based buffer overflow, on a system running an application compiled by ASN1C, via crafted...

The vulnerability of the ASN1_TFLG_COMBINE implementation in the OpenSSL library allows a hacker to extract sensitive information from the process’ memory.

The vulnerability of the ASN1TFLGCOMBINE implementation crypto/asn1/tasndec.c in the OpenSSL library is related to the lack of protection for service data. Exploiting this vulnerability could allow a malicious actor, operating remotely, to obtain protected information from the process’s memory...

AIX OpenSSL Advisory : openssl_advisory20.asc

The version of OpenSSL installed on the remote AIX host is affected by the following vulnerabilities : - A heap buffer overflow condition exists in the EVPEncodeUpdate function within file crypto/evp/encode.c that is triggered when handling a large amount of input data. An unauthenticated, remote...
